DDS(直接数字频率合成器)的整个工程文件,已在板子上运行通过,实现了正弦波、方波、三角波的调幅、调频，尚未实现调相，希望有志同道合者可一同完善！-DDS (direct digital frequency synthesis), the whole project documents, the board has been run through, achieved a sine, square, triangle wave amplitude, frequency, phase modula

实现信号的调制解调功能，包括各类调制如ASK(调幅),PSK（调相）,FSK（调频）。

gnuradio的简单例子，用python编写的模拟调幅型号的生成，里面有代码，和详细的注释，实现的结果图-gnuradio simple example, the generation of analog amplitude modulation model, which has the code, and detailed notes, plans to achieve results
